The architecture of ancient Egypt includes some of the most famous structures in the world: the Great Pyramids of Giza and the temples at Thebes. Building projects were organized and funded by the state for religious and commemorative purposes, but also to reinforce the power of the pharaoh. The ancient Egyptians were skilled builders; using simple but effective tools and sighting instruments, architects could build large stone structures with accuracy and precision.

The domestic dwellings of elite and ordinary Egyptians alike were constructed from perishable materials such as mud bricks and wood, and have not survived. Peasants lived in simple homes, while the palaces of the elite were more elaborate structures. A few surviving New Kingdom palaces, such as those in Malkata and Amarna, show richly decorated walls and floors with scenes of people, birds, water pools, deities and geometric designs.Important structures such as temples and tombs that were intended to last forever were constructed of stone instead of bricks. The architectural elements used in the world's first large-scale stone building, Djoser's mortuary complex, include post and lintel supports in the papyrus and lotus motif.

The earliest preserved ancient Egyptian temples, such as those at Giza, consist of single, enclosed halls with roof slabs supported by columns. In the New Kingdom, architects added the pylon, the open courtyard, and the enclosed hypostyle hall to the front of the temple's sanctuary, a style that was standard until the Graeco-Roman period. The earliest and most popular tomb architecture in the Old Kingdom was the mastaba, a flat-roofed rectangular structure of mudbrick or stone built over an underground burial chamber. The step pyramid of Djoser is a series of stone mastabas stacked on top of each other. Pyramids were built during the Old and Middle Kingdoms, but later rulers abandoned them in favor of less conspicuous rock-cut tombs.
